NVS Species Code

TEUPAR

The National Vegetation Survey (NVS) Databank is a physical archive and electronic databank containing records of over 94,000 vegetation survey plots - including data from over 19,000 permanent plots. NVS maintains a standard set of species code abbreviations that correspond to standard scientific plant names from the Ngä Tipu o Aotearoa - New Zealand Plants database.

Structural Class

Synonyms

Teucridium parvifolium var. luxurians Cheeseman,

Distribution

Endemic to New Zealand, occurring sporadically from Northland to Southland, but commoner in the east of both islands.

Habitat

Along fertile stream sides and river terraces in lowland dry forest and podocarp-hardwood forest; occasionally on forest margins, clearings and amongst scrub.

Features

A small-leaved shrub to 2 m. Young stems are orange or brown, square in cross-section and finely hairy. Leaves are in opposite pairs, round, dull green or brown-green; up to 12 mm long on stalks of equal length. Flowers are small (8 mm diameter), white (rarely bluish) with 5 irregular petal lobes. Fruit is a group of 4 seeds held within a persistent calyx.

Similar Taxa

Small, round-leaved Coprosma species are similar, but easily distinguished by their round or oval stems, leaf domatia (or pits in the leaf near the midrib) and a small, pointed ‘stipule’ running across the stem between each leaf pair. Neomyrtus pedunculata has square stems, but they are hairless while the leaves are shiny and gland-dotted.

Flowering

Flowering occurs from October to January.

Flower Colours

White

Fruiting

Fruiting from December to March.

Propagation Technique

Easy from fresh seed and semi-hardwood cuttings. A very hardy shrub which is tolerant of a wide range of habitats, soils types and moisture regimes.

Threats

Forest clearance, rural development, stock and feral animal browse, invasive weeds.

Chromosome No.

2n = 64

Where To Buy

Occasionally available from commercial nurseries. An attractive shrub which should be more widely grown.
